SPS injection kicker system: 2023 operational experience and upgrade proposals for high-luminosity LHC
/ Favia, Giorgia (CERN) ; Zannini, Carlo (CERN) ; Standen, Dylan (CERN) ; Velotti, Francesco (CERN) ; Ducimetière, Laurent (CERN) ; Feliciano, Luis (CERN) ; Barnes, Michael (CERN) ; Diaz Zumel, Miguel (CERN) ; Trubacova, Pavlina (CERN) ; Kramer, Thomas (CERN) et al.
The SPS injection kicker system comprises twelve MKP-S (small aperture) modules and four MKP-L (large aperture) modules. An upgraded MKP-L magnet was installed in the SPS, during December 2022, in view of the higher beam intensity needed in the future for High-Luminosity-LHC. [...]

Mitigation of High Voltage Breakdown of the Beam Screen of a CERN SPS Injection Kicker Magnet
/ Barnes, Michael (CERN) ; Bartmann, Wolfgang (CERN) ; Díaz Zumel, Miguel (CERN) ; Ducimetière, Laurent (CERN) ; Feliciano, Luis (CERN) ; Kramer, Thomas (CERN) ; Namora, Vasco (CERN) ; Stadlbauer, Tobias (CERN) ; Standen, Dylan (CERN) ; Trubacova, Pavlina (CERN) et al.
The SPS injection kicker magnets (MKP) were developed in the 1970’s, before beam induced power deposition was considered an issue. These magnets are very lossy from a beam impedance perspective: this is expected to be an issue during SPS operation with the higher intensity beams needed for HL-LHC. [...]

Beam-Based Waveform Measurements of the CERN PS Injection Kicker

In the framework of the LHC Injectors Upgrade (LIU) project, a beam-based technique has been developed for measuring the waveform the CERN Proton Synchrotron (PS) horizontal injection kicker, named KFA45. The technique avoids the need for tedious magnetic measurements, especially when a spare magnet is presently unavailable and measuring the operational magnet with a magnetic field probe is complicated by integration reasons.

Impedance Studies of the LHC Injection Kicker Magnets for HL-LHC
/ Day, Hugo (CERN) ; Barnes, Michael (CERN) ; Feliciano, Luis (CERN)
The LHC injection kicker magnets (MKIs) experienced strong heating during the first operational run, identified as being caused by power loss due to wakefields induced by stored beam. Studies of the beam coupling impedance of the beam screen, a series of conductors embedded in a ceramic tube placed in the ferrite yoke to screen the ferrite from the beam, resulted in new design offering improved screening: this is predicted to reduce the heating to acceptable levels for operation with 25ns beam during Run 2 of the LHC.
